ЛЕГКОПРОЛЕТНОЕ СТРОЕНИЕ

FIELD: construction.SUBSTANCE: invention can be used in creation of viaducts, ferrying through small rivers, ravines, bridge carrying supports for passage through cars and railways. Light-span structure contains at least two parallel flat longitudinal trusses including, each, lower and upper belts from longitudinal load-bearing elements connected by vertical posts – half-frames. Lower and upper longitudinal load bearing elements of each truss are interconnected by transverse lower and upper load bearing horizontal bridges. In the cross-sections of the light-span structure, the vertical posts – half-timbered frames of the trusses together with the horizontal transverse upper and lower crosspieces between the trusses form closed bearing portal frames. On the lower bridges there are additional longitudinal elements – longitudinal girders of the lower belt. Additional lengthwise load-bearing elements are secured to upper webs – longitudinal girders of upper belt with total area of cross section equal to 90 % of cross-section area of additional lower longitudinal girders.EFFECT: simplification of track structure construction, reduction of material consumption at increase of carrying capacity and rigidity.4 cl, 11 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 710 915 C1 (51) МПК E01D 2/00 (2006.01) E01D 6/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК E01D 2/00 (2019.08); E01D 6/00 (2019.08) (21)(22) Заявка: 2019115587, 21.05.2019 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Серов Павел Валентинович (RU) Дата регистрации: 14.01.2020 Приоритет(ы): (22) Дата подачи заявки: 21.05.2019 (45) Опубликовано: 14.01.2020 Бюл. № 2 2 7 1 0 9 1 5 R U (54) ЛЕГКОПРОЛЕТНОЕ СТРОЕНИЕ (57) Реферат: Изобретение может быть использовано при создании виадуков, переправ через малые реки, овраги, мостовые несущие опоры для переходов через авто и железные дороги.

COMPOSITE RCC DECK AND PRESTRESSED PARABOLIC BOTTOM CHORD UNDERSLUNG OPEN WEB STEEL GIRDER BRIDGE SUPERSTRUCTURE

Composite decks increase bridge strength and stiffness. Prestressed composite open web steel girder has added advantage of high strength cable support. Results of typical 125 m span bridges having heights of 9.0 m, 10.0 m and 12.5 m, and another 50.0 m span and 2.5 m height are given. Member stresses and bridge deflections during erection remained safe. Average steel off take for the 125 m bridge is 2.65 t/m and for the 50 m span bridge it is 1.77 t/m for limiting live load deflection of Span/800. Its reserve strength is 3.2 times service condition live load. The girders are panel wise workshop fabricated, assembled at site, jacked up or crane lifted to secure over bearings. Connection of the cross members, and onsite deck casting in parts with stage wise bottom chord prestressing is carried out. Short to long span bridges for single or multiple lanes in road, rail, metro rail, and coastal link projects are feasible.

BRIDGE TRUSS, BRIDGE SPAN INCLUDING SUCH TRUSSES, AND METHOD OF CONSTRUCTING THE TRUSS

Bridge truss, bridge span including such trusses, and method of constructing the truss. Prefabricated transverse sections of a bridge are essentially constituted by a three-dimensional truss of prestressed high mechanical strength concrete without a deck. The prefabricated sections are placed in situ to build up a bridge span, and deck-constituting units are subsequently placed on the span after it has been assembled. The invention also provides the unit three-dimensional trusses constituted by bars (P1 to P30) of prestressed high mechanical strength concrete interconnected by assembly blocks cast in concrete. The invention is particularly applicable to bridge building using the cantilever technique and a guyed support beam.

TRUSS, ESPECIALLY FOR BRIDGE CONSTRUCTION

A prestressed truss for constructing bridges is supported at a number of points (1, 2) in order to form two series of truss elements (4a, 4b, 4c, ... 5a) in respect of each span. Each truss element comprises a top chord member (6a) of concrete and a bottom chord member (8a) of concrete, said members being connected together by means of bars (10a, 11a, 12a) forming an N-panel. The vertical bars (10a, 11a) are placed near the ends of the chord members and essentially resist tensile forces. The third bar (12a) resists compressive forces and is upwardly inclined in the case of the first series of truss elements (4a, 4b, ...) and downwardly inclined in the case of the second series of truss elements (5a, ...) located beyond a point M at which the shearing forces under continuous load are substantially zero.

Adjustable Modules for Variable Depth Structures

This disclosure presents a new strategy for modular construction: an adjustable module. This disclosure develops a new adjustable module comprised of a four-bar linkage which can form more efficient variable depth structures. Applications can include rapidly erectable bridges, roofs, buildings, and grid shells, among others. This disclosure provides specific detail related to rapidly erectable bridge applications for variable depth arch forms. Existing rapidly erectable, steel panelized bridge systems have limited material efficiency as they are comprised of rigid modules in a girder-type configuration. This disclosure shows that the module can form variable depth three- and two-hinged arches which increase the material efficiency. The module and other arch components can be made of standard rolled steel sections, thereby forming a versatile, kit-of-parts systems.

Lightweight modular, truss-deck bridge system

LIGHTWEIGHT MODULAR, TRUSS-DECK BRIDGE SYSTEM Abstract of the Disclosure A modular bridge system constructed of parallel, side-by-side bridge modules con-structed of components made from large pitch and depth corrugated plate. Each module has an upper chord plate, which ultimately defines the corresponding part of the bridge deck, a spaced apart, parallel lower chord plate and an inter-mediate, sinusoidal support structure defined by webs which have a width substantially equal to the width of the chord plates so as to define a continuous lateral support for the upper chord plates at intermediate points over the length thereof. Load distributing ribs secured to the underside of the chord plates only are placed at unsupported portions of the upper chord plates between attachment points for the webs and have a width substantially equal to the combined width of all modules to tie the modules to each other and to distribute vehicular (point) loads over a relatively wide lateral extent of the chord plates. Also disclosed is a high strength mounting of lateral guard rails for the bridge, a method for constructing and erecting the modules, and the incorporation of the modules in more intricate bridge structures such as arch-type bridges.

Moment-resisting joint and system

The present invention is directed toward a novel moment resisting connection system, for use, but not limited to, with a pony-truss bridge system. The connection system comprises multi-hollow sections that can be, but are not limited to, extruded aluminum and a joint or node connector that can be casted, milled, forged or made by any other means. For example, a moment transferring assembly may comprise a connector node element, having a plurality of cavities, and a plurality of framing members, generally elongated, insertable into a respective cavity of the connector node. A mechanical fastener can be mounted between the connector node element and the framing member and maintain them engaged with one another. The connector node element includes a channel for receiving an elongated load carrying chord. The fastener has a tool engaging head accessible through the channel such that when the chord is received, removal of the fastener is precluded.
